Peret-O-25 is a nonionic surfactant with stable chemical properties. However, because it is in solid form (white to slightly yellow flakes or blocks) and is prone to moisture absorption, controlling the storage environment is crucial for maintaining product quality. This product is non-toxic and non-flammable, and it is managed under general chemical transportation conditions. Nevertheless, storage specifications must be strictly followed to ensure product performance is not affected.
Within the recommended storage temperature range (5°C–40°C), the product maintains stable physical and chemical properties. If the ambient temperature falls below 5°C, the product may become cloudy or solidify, which is a normal physical change and not a sign of degradation. Simply warm the product to room temperature and stir evenly to restore its original performance without affecting its quality for use.
Under specified storage and transportation conditions, the shelf life from the date of manufacture is 24 months (two years). Products that exceed the shelf life can still be used if they pass re-inspection and meet all quality indicators. It is recommended that users perform necessary quality testing near the end of the shelf life to confirm that product performance meets process requirements before use.

For ease of daily use, it is recommended that the product be stored in a designated chemical storage area near the production workshop to avoid frequent handling. Since the product is in solid form, it should be dissolved using hot water above 60°C before use. Preparing a stock solution in advance helps with accurate metering. After opening, any unused product should be promptly resealed in the package to prevent moisture absorption and caking, which can affect subsequent weighing and dissolution efficiency.
During transportation, the product should be covered to prevent sun exposure, rain, and moisture. If the product becomes hard or abnormal in appearance due to low-temperature transport in winter, simply let it sit in a warm warehouse to return to normal temperature; this will not affect product quality or usage.
